Calling right distributing method in trunking communication

Abstract

The invention relates to a speaking right allocation method in trunking communication in the field of trunking communication technology. The user terminal sends a registration request carrying the message of the speaking right allocation method pre-selected by the user, that is, the push-to-talk PTT server saves the registration request message, and when the user terminal initiates a call, the PTT server uses the speaking right allocation method carried in the registration request. Allocate speaking rights to user terminals. The method of the present invention enables the user to select a suitable speaking right allocation method according to his actual needs during the registration application process before calling, which improves user experience and enables the user to know in advance possible consequences in the speaking right allocation process.

Description

technical field [0001] The invention relates to the technical field of trunking communication, in particular to the allocation of speaking rights in trunking communication. Background technique [0002] Digital trunking is the main body of today's dedicated wireless communication. It also belongs to the category of mobile communication, but it can integrate functions such as command and dispatch, telephone, data, short message, and multimedia images. Compared with public and global mobile communications, it has a series of special functions. Especially in scheduling, network structure and security control, etc., it has its unique characteristics and complexity, such as fast scheduling group call, broadcast, unicast, forced demolition, forced insertion, abbreviated addressing, priority call, delayed entry, environment detection, etc. Listening, control transfer, dynamic reorganization, automatic retransmission, VPN (virtual private network) networking, etc. Many of these spe...

Problems solved by technology

[0014] The shortcoming of above-mentioned right-to-speak control method is: when distributing right-of-speaking, does not consider whether there is someone currently answering the speaker's voice, and the speaker starts to speak after receiving the Floor Grant message, and he cannot confirm whether there is an answering user, and if the called user delays If you cannot access or the PTT server sends multiple invitations, the called user cannot access, and the speaker's voice will be discarded. Since the speaker's voice has already used the wireless channel at this time, the PTT server will collect the speaker's billing information

[0022] The above speaking right allocation process has to consider whether there is a listener to access, so the speed of speaking right allocation is relatively slow, which affects the speed of the calling party to obtain the speaking right, resulting in a certain delay in the call process, which cannot meet the requirements of the conversation right in the trunking communication. Dispensing Speed ​​Requirements

[0023] It can be seen from the above description that the existing voice right allocation scheme is opaque to the user, that is, the user does not know that the scheme used will cause voice loss or delay, so the user cannot choose the voice right allocation scheme that suits him or her according to actual needs.
